Hello everyone. Today I am teaching you how to jailbreak your old iPhone 3GS. Personally, I think everyone should have owned a 3GS. I love old iphones, and the 3gs isn't an exception! Lets start. JB'ing with redsn0w! The first method I am showing you involves redsn0w. before starting: 1. backup data. i will not be responsible for data loss. 2. update your iphone to ios 6.1.6. this guide may or may not work on ios 6.1.3. 1. download redsn0w. 2. go to http://www.ipswdownloader.com/ and select iPhone - iPhone 3GS - iOS 6.0. ONE MORE TIME: iOS 6.0! Not any other version! 3. when the download is done, connect your iphone to the computer. if itunes opens, just close it again. 4. open redsn0w. 5. go to extras and choose select IPSW. 6. navigate to the ios 6.0 ipsw downloaded in step 2. 7. Go back to the main page and choose jailbreak and install cydia, or something to that affect. each version is different! 8. BEFORE clicking next for help entering DFU mode, follow these steps to put your iphone in dfu. http://www.iclarified.com/1034/how-to-put-an-iphone-into-dfu-mode Once the device is in DFU, redsn0w will automatically start. 9. Depending on what version of redsn0w you have, a dialog box for choosing preferences may show. just choose whatever custom items you want installed. if you don't know, click next and ignore the option. Your iPhone is now jailbroken!
